PROBLEM TO BE SOLVED: To provide a water-cooled busbar wherein it is possible to prevent crevice corrosion that may occur between end faces of two busbar constituent members adjoining to each other in the direction of length and thereby reduce the electrical resistance between these busbar constituent members. SOLUTION: End faces 2, 2 of two busbar constituent members 1, 1 made of aluminum or aluminum alloy comprising a water-cooled busbar 40A are disposed at a distance in-between. The busbar constituent members 1, 1 are electrically connected with each other through a conductive member 20. An opening 3a of a cooling water passage 3 is formed in the end face 2 of each busbar constituent member 1. These openings 3a, 3a are coupled with each other through a flexible cooling water duct 10 so that they communicate with each other. COPYRIGHT: (C)2010,JPO&INPIT
